The increasing popularity of cloud computing in distributed computing environment may have positive as well as negative effects on the data security of service consumers. This paper highlights some major security issues existing in current cloud computing environments. The primary issue to be dealt with when talking about security in a cloud is protection of the data. The idea is to construct a privacy preserving repository where data sharing services can update and control the access and limit the usage of their shared data, instead of submitting data to central authorities, and, hence, the shared-disk database architecture will promote data sharing and privacy of data. This paper aims at simultaneously achieving data confidentiality while still keeping the harmonizing relations intact in the cloud. Our proposed scheme enables the data owner to delegate most of computation intensive tasks to cloud servers without disclosing data contents or user access privilege information.
